我有这样的WebViewClient依恋WebView:
webView.setWebViewClient(new MyWebViewClient());
这是我的实现MyWebViewClient:
private class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
webView.loadUrl(url);
return true;
}
}
我给了WebView一个URL来加载via loadUrl().如果我a href...在页面中有一个link(),我的shouldOverrideUrlLoading方法被调用,我可以拦截链接点击.
但是,如果我有一个方法的表单,则不调用POST该shouldOverrideUrlLoading方法.
我在这里注意到了一个类似的问题:http://code.google.com/p/android/issues/detail？id = 9122这似乎建议覆盖postUrl我的WebView.但是,此API仅从API级别5开始提供.
如果我在API级别4,我该怎么办？有没有其他方法来拦截表格帖子？
在我的主布局文件中,我有一个RelativeLayout,权重为1(基本上显示一个地图)在LinearLayout上方,权重为2,这样声明:
<LinearLayout
android:id="@+id/GlobalLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="@+id/UpLayout"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1" >
</RelativeLayout>
<LinearLayout
android:id="@+id/DownLayout"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="2"
android:orientation="vertical" >
</LinearLayout>
</LinearLayout>
DownLayout包含一个项目列表,当我点击一个项目时,我想将DownLayout的权重更改为4,因此上部布局(地图)仅占屏幕的1/5而不是1/3.
我设法通过更改LayoutParams来实现:
LinearLayout linearLayout = (LinearLayout) mActivity.findViewById(R.id.DownLayout);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT);
params.weight = 4.0f;
linearLayout.setLayoutParams(params);
它有效,但我不满意,变化太直接,没有过渡,而我希望它是顺利的.有没有办法使用动画？
我发现了一些使用ObjectAnimator来改变weightSum的例子,但它并不想要我想要的(如果我只改变这个属性,我在我的向下布局下面有一些空闲空间):
float ws = mLinearLayout.getWeightSum();
ObjectAnimator anim = ObjectAnimator.ofFloat(mLinearLayout, "weightSum", ws, 5.0f);
anim.setDuration(3000);
anim.addUpdateListener(this);
anim.start();
有没有办法使用ObjectAnimator(或其他东西)来做到这一点？
谢谢 !

我想知道
在mongo命令行中,我可以运行
db.my_collection.stats()
我需要获取我的收藏统计数据,Python所以我试过了
from pymongo import MongoClient
client = MongoClient()
db = client.test_database
collection = db.test_collection
collection.stats()
但我明白了
TypeError: 'Collection' object is not callable.
If you meant to call the 'stats' method on a 'Collection' object it is failing because no such method exists.
这是因为pymongo不支持这种方法.如何发送原材料mongoDB到命令mongo通过Python？
我创建了一个用户模型Devise,每当我使用时,rake db:migrate我都会遇到以下问题:
== DeviseCreateUsers: migrating ==============================================
-- create_table(:users)
rake aborted!
An error has occurred, this and all later migrations canceled:
undefined method `database_authenticatable' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x00000103fa1ff0>

(See full trace by running task with --trace)
我用完全跟踪,--trace function但似乎无法弄清楚问题是什么.这是迁移文件:
class DeviseCreateUsers < ActiveRecord::Migration
def self.up
create_table(:users) do |t|
t.database_authenticatable :null => false
t.recoverable
t.rememberable
t.trackable

如何TextView在Java代码中将android的文本外观设置为大？有一种方法setTextAppearance(),但我不知道如何使用它.
